Au137(SR)56 nanomolecules: composition, optical spectroscopy, electrochemistry and electrocatalytic reduction of CO2Electronic supplementary information (ESI) available: Detailed synthetic conditions, ESI mass spectra, optical spectra, and powder XRD of purified NMs. See DOI: 10.1039/c4cc03424d

Au 137 (SR) 56 , a nanomolecule with a precise number of metal atoms and ligands, was synthesized. The composition was confirmed by MALDI and ESI mass spectrometry using three unique ligands (-SCH 2 CH 2 Ph, -SC 6 H 13 , and -SC 4 H 9 ) and nano-alloys with Ag and Pd. The electrocatalytic properties...

Description
Summary:Au 137 (SR) 56 , a nanomolecule with a precise number of metal atoms and ligands, was synthesized. The composition was confirmed by MALDI and ESI mass spectrometry using three unique ligands (-SCH 2 CH 2 Ph, -SC 6 H 13 , and -SC 4 H 9 ) and nano-alloys with Ag and Pd. The electrocatalytic properties were tested for CO 2 reduction. Au 137 (SR) 56 has been synthesized with three ligands and two nano-alloys, isolated and assigned using mass spectrometry tools. UV-Vis-NIR absorption, voltammetry and CO 2 reduction properties are also reported.
